MCQ: Tensile strain is equal to

  1. Force per unit area
  2. Force per unit volume
  3. Extension per unit length
  4. Force per unit length


MCQ: Hooke's law states that

  1. the extension is proportional to the load when the elastic limit is not exceeded
  2. the extension is inversely proportional to the load when the elastic limit is not exceeded
  3. the extension is independent of the load when the elastic limit is not exceeded
  4. load is dependent on extension


MCQ: Dimensions of strain are

  1. [L]
  2. [M] [L]-1 [T]-2
  3. [L]-1
  4. It's a dimensionless quantity


MCQ: At ‘yield point’ of a copper wire

  1. the load hasn't exceeded the elastic limit yet; so, Hooke's law applies
  2. the load has already exceeded the elastic limit and the material has become plastic
  3. even the plastic stage has passed and the wire has snapped already
  4. Like Brass and Bronze, Copper has no yield point


MCQ: Substances that elongate considerably and undergo plastic deformation before they break are known as

  1. brittle substances
  2. breakable substances
  3. ductile substances
  4. elastic substances
